JSONP is a technique that allows you to transfer JSON data across multiple domains.
jQuery now supports JSONP natively - if you attempt to load JSON (via $.getJSON or $.ajax) from a remote URL then an extra callback will be provided for the server to interpret. Additionally, if the server requires a special field for specifying your own callback name you can provide it by having a "=?" in your query string.
Example:
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
$(document).ready(function(){
$.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any&format=json&jsoncallback=?", function(data){
$.each(data.items, function(i,item){
$("<img/>").attr("src", item.media.m).appendTo("#images")
.wrap("<a href='" + item.link + "'></a>");
if ( i == 3 ) return false;
});
});
});
</script>
<style>img{ height: 100px; float: left; }</style>
</head>
<body>
<div id="images"></div>
</body>
</html>
